The CHP says on Sunday night, Arroyo was the driver of a 2004 Nissan Titan that hit a guardrail on Interstate 5 in San Diego then hit a palm tree and ended up on its side atop a concrete retaining wall. Arroyo got out of the pickup and tried in vain to pull out the boy then got back inside and freed him from his child seat, but the boy fell about 10 feet to a concrete sidewalk below.
